T 0 aZZ whom it may concern:

Be it known that I, WVILLIAM TrroMAs, a citizen of the United States,residing at Victoria, in the county of Lunenburg, State of Virginia,have invented certain new and useful Improvements in Babbitting andBrassing Machines; and I do hereby declare the following to be a full,clear, and

exact description of the invention, such as will enable others skilledin the art to which I it-"appertains to make and use the same.

' This invention relates to new and useful improvements 111 machines forbabbitting and brassing gibs or keys of the cross-head slides oflocomotive pitmen or the like.

One object of the invention is to provide a novel and improved device bymeans of which cross-head gib or key can be lined with Babbitt-metal "orbrass to the thickness desired, and without the ultimate ne cessity ofplaning any rough or jagged edges.

I Another object is to provide a device of this character by meansofwhich the 'babbitt or brass, which lines the side walls'of thecross-head gib, may bemade of a' different, thickness from that inthe-bottom wall of the or brassing machine made in accordance with myinvention, in proper position ready for the reception of the moltenbabbitting or brassing metal.

Figure 2 is a top planview of the same. Figure 3 is a verticaltransverse center sectional view on theiline 3+3 of Figure 2.

Figure 4 is a vertical longitudinal center sectional view on the line 44of Figure 2.

Referring particularly to the accompanying drawing, there 1s shown asupporting frame which consists of a pair of elongated metal plates 10,disposed on their longer edges and arranged in parallel relation, withtransverse bolts 11 disposed through the end portions thereof and havingnuts 19. thereon engaged with the opposite side faces p 1,452,819;PATENT OFFICE.- Q

of the plates. The plates are thus held in I proper spaced relation. Inthe, upperfedge of each of the plates, and adjacent oneend thereof,there is formed a pair of notches 13,

and in theupper edge adjacent theiother l end'there isformed a singlenotch 14:. In

the lower edge of eachdof the plates below the notches 13, arenotches-15, the same being arranged however in staggered relation tothenotches 13. formed inthe lower edge of each of'the plates below andoffset from/the no'tche'sfl l.

The back f the cross-head 'gib' 17 is formed with alongitudinal centralrib 18, which is arranged to lie between the upper portions of the P es10 and the remaining portion ofthe back of the gib torest onthe'upper'edges of the plates '10. Some-- times, in removing the gibfrom the crosshead the ends thereof will become slightly,

battered and thus result in the edges at the end of the gib turning downto a slight degree. hen the .gib is "disposed on the plates 10, thisdown-turned battered portion would rest on the upper edges of the platesand'thus prevent the gib from lying level.

A single notch 16 is e,

It, is with thisin view thatthe notches 13,,

14, 15 and 16 are provided, the downturne'd battered ends of the gibpassing intov the.

notches so that the gib will rest flatly on the upper edges of theplates 10.

A pair "of metal blocks -l9 are placed transversely of the frame so thatthey rest on the upper edges of "the plates 10 and against the end facesof the gib, said blocks being of a proper depth or thickness to riseabove the upper face of the bottom Wall of the channel of the gib. Apair of transverse bars 20 of slightly greater length than the blocks 19are disposed transversely of the frame, on the upper edges of the plates10 and outwardly of the blocks 19. The ends ,of the bars 20 are providedwithopenings through which are disposed the threaded ends of the rods21, nuts 22 being engaged on the ends of the rods outwardly of'the bars20. One of thebars 20 bears against bears against the adjacent verticalface of the other block 19, andhas on itsother end a crank handle 24, bymeans of which it may be rotated, for the purpose of clamping the blocks19 firmly against the ends of the gib. A pair of wedge blocks 25, areplaced on ltheouter vertical face of one of the blocks 19, and threadedthrough the center of the other bar 20 is a clamping screw 23, whlch theupper faces of the blocks 19 over the channel of the gib, the upperfaces of the wedge blocks being graduated so that they may be movedlongitudinally with respect to each other, to move their outer edgestoward and away from the side walls of the channel of the gib.The'spaces between the outer faces of the wedge blocks and the innerfaces of the side walls of the gib will be the thickness of the liningof babbitt or brass of the side walls. It will be noted that the endportions of the blocks rest on the blocks 19, and are thus held elevatedabove the bottomwall of the channel of the gib. This distance or spacerepresenting the thickness the babbitt or brass will be on the bottom ofthe gib channel.

Vhen the wedge blocks 25 have been properly placed in the gib, theoperator pours the molten Babbitt-metal or brass between the'side wallsof the gib andthe wedge blocks, this metal running down into the channelof the gib beneath the wedge blocks and to the blocks 19, which blocks19 act as end walls for the Babbitt or brass lining. Should the operatordesire a thicker Babbitt or brass lining in the bottom of the gib,additional plates 26 are placed on top of the blocks 19, so that the endwalls of the Babbitt or brass will be permitted to rise to a greaterheight above the bottom wall of the channelof the gib.

Each of the blocks 25 is provided with a handle 27, to permit the sameto be lifted into and out of the gib. When the metal has set or cooled,and it is desired to remove the wedge blocks 25, the upstanding lugs 28,formed on the upper faces of the wedge blocks 25, are struck with ahammer or other tool to drive either one of the wedges longitudinally ofthe other. The wedges may then be easily lifted out.

The rods 521 permit adjustment so as to accommodate gibs of differentlengths.
